64: non-mandatory-script-verify-flag while broadcasting P2WPKH Bech32 with specific inputs

Question

Note: This happens with specific input, even though I've used the same code for other inputs and it works.

I have created a raw transaction using the following unspent:

Array
(
    [0] => Array
        (
            [txid] => 108544730bfaeccca0de66eda8546a33403899fb508bee582f1d9e1628ec0695
            [vout] => 1
            [scriptPubKey] => 0014194eef88d8428a4af66177779d0844d66d743e5d
            [amount] => 0.000560
            [address] => tb1qr98wlzxcg29y4anpwame6zzy6ekhg0jadfmrgr
            [redeemScript] => 
        ) // this i'm not able to spend.

    [1] => Array
        (
            [txid] => 5bda1b65ff7cb3c80f09f797debb2bf1749d22332e984ba6377a0c7cac30aed9
            [vout] => 0
            [scriptPubKey] => 00141f09edebd56ffadd0c1834d048c8a416d5418f68
            [amount] => 0.100000
            [address] => tb1qruy7m674dlad6rqcxngy3j9yzm25rrmgm9x3d5
            [redeemScript] => 
        )

Sendrawtrasnaction response: 64: non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation)

Answer 1

First of all, these are not P2SH-P2WPKH, these are normal P2WPKH outputs. They are not related to P2SH at all.

The problem here is probably that the amount is incorrect. If you are providing the previous output data yourself, then the amounts is incorrect. You have it as 0.000560 but the actual amount is 0.00055999. Since Segwit commits to the amount in the signature, having the wrong amount means that the signature signrawtransaction creates will be invalid which thus results in this error.
